M27 between the stars

A new image taken in Meldert, Belgium of M27. This is the full APS frame of the ASI2600MC sensor in combination with the Esprit 120mm F/7 @ 840mm focal length.

Subs are 300 seconds at Gain= 0 (18 subes or 90 minutes, under a mediocre sky. Click on the image for a marger view)

M27 Continued

I’m not sure what to think of this image. There’s a fair amount of detail, also the outer regions are visible. It’s fake colors anyway so I tried to balance colers for an esthetic appearance combined with a maximum of detail. The thing is, when you look at the individual B/W images, they seem far better in terms of quality, smoothness, noise and detail. It’s when combing them into color that they suddenly require maximal processing to get something out of it. 

Skies were not very good, lot’s of high altitude clouds and contrails. The data has been gathered over maybe 6 or 7 nights for the past weeks.

I have RED and GREEN filtered data still that I did not use in this combination. The total integration time is over 18 hours. I guess lots of rain and clouds should come over to get me reprocessing again? I’m not sure what to think of this image. There’s a fair amount of detail, also the outer regions are visible.

M27 in H-Alpha light

This picture shows the well-know classic object of the Dumbell nebula, or M27. I could image this object for more then 10 hours on several clear nights lately, with 8 hours of H-Alpha narrowband (7nm) and 2 hours of RGB.
